- Comment on Is it cheaper to use a plug-in oil radiator to eat an individual room, or run the central heater to heat an individual room and living room? 2 weeks ago:
I’m not an HVAC technician so I wouldn’t know exactly, but I think there’s two things to consider: static pressure and duty cycle. Static pressure is the fan working hard to spin which causes wear on bearings. Duty cycle is how long the machine runs. If your duty cycle is too low then the machine is turning on and off quickly which is bad.
You could look at the size of the unit and there’s some rules of thumb that translate size, climate, and square footage and there are online calculators you can use. I think the only way to know for sure is to measure the pressure drop across the intake and outflow and see what the fan motor is rated for.

Depends on the unit and whether it was over sized or under sized for the space, but restricting 60℅ air flow is a lot.

- Comment on YSK that Amazon has different prices for different people 4 weeks ago:
Yeah there’s a few reasons why the offer that wins the buy box (the term for which merchants offer is shown to the customer prominently) and is complex, but I wouldn’t consider it particularly sinister or designed to mislead. If one person has prime and the other doesn’t, it might weight more towards a prime offer which may be more expensive, a price from a merchant may have changed, or gone out of stock.
- Comment on Three Mile Island owner seeks $1.6 billion federal loan to restart nuclear plant for Microsoft AI facility 1 month ago:
I have my doubts that a company would be able to just abandon a live and operational nuclear power plant. I’m no nuclear or power engineer, but I am familiar with data center power consumption. There are companies in the region that would absolutely build more data centers, but are power constrained from the utility companies in the area, that are not just for AI, but for general compute. Even then, it’s low carbon production energy. If you have a ton of excess power, just start forcing high carbon production facilities in the area to close and now you’ve greened the grid.
- Comment on Three Mile Island owner seeks $1.6 billion federal loan to restart nuclear plant for Microsoft AI facility 1 month ago:
While I’m not a fan of the loan, I actually think that’s its a good thing because if Microsoft can break through some of the excessive red tape on nuclear plants then they’ll bring this online and hopefully prove that nuclear power can be safe and a good source of large amounts of power, when the huge demand for AI dies down, then maybe they’ll keep the plant around and provide power to the grid.
- Comment on Tesla issues 5th recall for the new Cybertruck within a year, the latest due to rearview camera 1 month ago:
Kind of but it’s not fair to put it all on the manager. Multiple decided to hire the person. Somebody else approved that code review. People approved the technical design. Why didn’t the tech lead raise concerns with the manager about someone’s underperformance, etc. it’s unfair to just put all blame on the manager.
The idea of extreme ownership is about not saying “not my problem I won’t do anything” or blaming your reports. It’s about saying I can and should do anything and everything in my ability to fix problems.
- Comment on DeArrow is an open source browser extension for crowdsourcing better titles and thumbnails on YouTube. 2 months ago:
This is my biggest challenge with this extension. What’s clickbait to one person is not to another. Several times I’ve come across titles that get mangled when rewritten to lose key points. Or the image gets replaced with a random screen grab. There’s a difference between somebody doing the YouTube face and a title with “the craziest stunt you’ve ever seen” and an artist photo with a title saying the “a crazy stunt jump through a burning hoop”.
One person could still say “crazy” makes it clickbait, but having some adjectives are fine
- Comment on Microsoft donates the Mono Project to the Wine team 2 months ago:
Ah yeah. Mono didn’t support WPF, but Mono did support running WinForms apps natively on Linux without using Wine.
- Comment on Microsoft donates the Mono Project to the Wine team 2 months ago:
.net core is the future but Mono is still important for running legacy .net framework applications like ones that use WinForms or WPF. That’s pretty much it. Anything new should go straight to .net core.
- Comment on We finally know what caused the global tech outage - and how much it cost 3 months ago:
They could and clearly they should have done that but hindsight is 20/20.
- Comment on Home routing and encryption technologies are making lawful interception harder, Europol warns 4 months ago:
For those who aren’t aware. This is talking about when cell phones roam into other networks, they now encrypt the traffic back to the home provider which means law enforcement struggle to tap it (legally or illegally).

- Comment on Do I Need to Harden SSH over Tor? 7 months ago:
Accidentally typo your password and get blocked. And if you’re tunneling over tor, you’ve blocked 127.0.0.1 which means now nobody can login.
- Comment on Ticketek ‘glitch’ appears to re-sell fan’s $659 ticket for Taylor Swift concert — “They said, ‘someone else has it, we don’t know who, we can’t check or track who has your ticket’” 9 months ago:
Doubtful. TicketMaster is there to take the bad PR but was designed to get as many fees and funnel part of those fees to the artist. Yes TM has deals with Live Nation that basically force big artists to use them because they have the big stadiums, but Taylor Swift is a massive artist she has tons of lawyers and can negotiate fees.
As much as I love Taylor Swift, I have no doubt that she is massively benefiting from the high ticket prices.
- Comment on Help with NGINX? so close... 10 months ago:
I don’t fully understand what you’re saying, but let’s break this down.
Since you say you get an NGINX page, what does your NGINX config look like? What exactly does the NGINX “login page” say? Is it an error or is it a directory listing or something else?
- Comment on Microsoft lays hands on login data: Beware of the new Outlook 1 year ago:
It’s true that Mozilla does collect telemetry and that Mozilla Corp is for profit, however Mozilla Corp is owned by Mozilla Foundation. That ownership structure is either a way to get around limitations on non profits, or its an opportunity for the Foundation to directly influence the Corp to be better.
However, I’ll still use Firefox/Thunderbird because: Usage stats such as number of accounts or filters is in no way comparable to my username and password. One is basic metadata and stats, the other is a massive risk. You can opt out of the telemetry, the only way to opt out of sharing your password is to not use the new Outlook.
I take a more pragmatic approach to privacy based on my trust. I understand the value of telemetry, but change it depending on the company. Big Tech I have less trust in, Mozilla, while they have issues, are on average far better for privacy vs big tech.
As a developer, I understand the value of telemetry and the risks that come with collecting any data. I pick Firefox because it challenges the homogeney of Google’s influence and it looks like I’m going to pick Thunderbird because I’ haven’t seen a better option.
- Comment on LinkedIn user data leaked: Database shows emails, profile data, phones, full names, and more confidential info. 1 year ago:
That’s not because you have a wildcard. That’s because you need to implement DKIM, DMARC, and SPF records to prevent others from using your domain name to send mail.
- Comment on Unpacking Amazon's stealthy mass layoff strategy in Seattle 1 year ago:
Amazon corporate employees get RSUs which are stocks, not options. After the new hire RSUs go away, you end up with two vest dates a year and new comp offerings start the following year (so in 2024 you’ll see new money in 2025 plus a small base salary bump that goes in effect that month).
Tech salaries are frequently stock based, but Amazon’s is unusual in that it’s only twice a year, and bumps start the following year, and they recently made the change to do 2 year offers instead of 3 years.
- Comment on Docker containers can no longer communicate with the host's local network 1 year ago:
If you’re running Docker for servers not development, then you can make Hyper-V work. I used to do that before I got a separate Linux server.
Just setup a network adapter that gets bridged to your Ethernet adapter, then create a VM that uses that bridged adapter. The Linux VM will appear like its another computer on your LAN and you can use Docker with host Network.
- Comment on Google's Web DRM is Worse than I Thought... 1 year ago:
Attestation depends on a few things:
- The website has to choose to trust a given attestation provider. If Open Source Browser Attestation Provider X is known for freely handing out attestations then websites will just ignore them
- The browser’s self-attestation. This is tricky part to implement. I haven’t looked at the WEI spec to see how this works, but ultimately it depends on code running on your machine identifying when it’s been modified. In theory, you can modify the browser however you want, but it’s likely that this code will be thoroughly obfuscated and regularly changing to make it hard to reverse engineer. In addition, there are CPU level systems like Intel SGX that provide secure enclaves to run code and a remote entity can verify that the code that ran in SGX was the same code that the remote entity intended to run.
If you’re on iOS or Android, there’s already strong OS level protections that a browser attestation can plugin to (like SafetyNet.)
- Comment on Does self hosting an instance of a federated service, like lemmy, effectively act as a VPN for your account? 1 year ago:
What is your threat model or goal? It could hide the device you use to connect to the instance, however a lot of actions you do on Lemmy, including all upvotes, are public to other instances.
